1. The reason why silver jewelry turns black
The blackening of silver jewelry is a normal natural phenomenon, because sulfur and oxides in the air and other natural media have a certain corrosive effect on silver. After wearing silver jewelry for a long time, the combination of sulfur and silver will form a layer of black silver sulfide film on the surface of silver jewelry, which begins to appear as some fine spots. After the vulcanization phenomenon intensifies, it slowly spreads into pieces, forming what people usually call silver scale, which turns black and affects the surface gloss of silver jewelry. People usually mistake it for fading.
The chemical reaction equation is: 4Ag+H2S+O2=2Ag2S+2H2O

2. How to clean silver jewelry after vulcanization?
Squeeze a little toothpaste, add a little water to make a rich foam, wipe it with a soft cloth until it is bright, the gap can be brushed with a soft-bristled toothbrush, and then rinsed with water. For complex components and chains, you can put it in foamed toothpaste water and rub it repeatedly, and then rinse it with water. When the vulcanization is serious, you can use professional silver washing water to clean it. Although imported silver washing water claims to be “silver-free”, silver washing water is a chemical agent after all, and it is recommended not to use it unless necessary.

3. 银饰日常如何保养?
较好的银饰保养方法是天天配戴,因为人体的油脂会使银发出温润自然的光泽(当 然也有人例外,有人的汗液中本身含有使银变黑的成分).佩戴时每天要用软布或 擦银布擦拭银饰表面,以保持光泽及干燥.不佩戴时用软布轻拭表面以清除水分和 污垢,置放与密闭袋子中,防止银饰表面与空气接触而氧化变黑.
